My Cobra has a 427 SO the car weighs 2800 lbs with a full 20 gal tank and me inside (260 lbs) I think that the power weight ratio is more than enough unless you have a death wish or not in touch with reality. How much power is enough? I guess it is never enough for some. With my current set up my car was dynoed at 550 hp, I am more than happy with that the engine has never been bored from std bore.
My .02 cents on this topic and my personal opinion, not intended for it to become an argument.

Lou, II
